  • Patent number: 7551652
    Abstract: A shared modulator applies radial stress to the polarization-dependent fiber chains to induce birefringence and simultaneously Q-switch two or more fiber lasers. Multiple temporally overlapping pulsed beams can be generated with pulses <100 ns and even <30 ns with repetition rates from 50 Hz up to 650 KHz. A pair of Q-switched fiber lasers at slightly different wavelengths being well suited to provide a low-frequency light source through difference frequency generation (DFG) by nonlinear optical materials.

  • Patent number: 7539221
    Abstract: A fiber-laser-based implementation of a Gigahertz source through difference frequency generation (DFG) by nonlinear optical (NLO) materials is compact, tunable and scalable. A pair of pulsed fiber lasers, preferably single-frequency, generate output pulses at frequencies ?1 and ?2 that overlap temporally. A beam combiner combines the laser outputs and routes the combined output to a GHz generator head where a nonlinear interaction process in the NLO material generates GHz radiation.
